Question: Let A 36000 3 2 7 8 -1 5 5 -2 9 - 0 2 -2 -6 0 0 3 4 0 0 0

Let A 36000 3 2 7 8 -1 5 5 -2 9

Let A 36000 3 2 7 8 -1 5 5 -2 9 - 0 2 -2 -6 0 0 3 4 0 0 0 Then the cofactors C12 C22 and the determinant det(A) = det(A) Recall Cramer's Rule: Given Ax = b. if det(A) 0 then = where A, is obtained from A by replacing its ith col det(A) If Ax = [14 -4 400] then 23 = . (Simplify your answer!)
